3 kiểu phỏng vấn interview khi thu thập dữ liệu
- Unstructured interview — free-flowing conversation, no fixed questions, the interviewer follows wherever the participant leads. Most flexible, most unpredictable.
- Semi-structured interview — a prepared question guide, but the interviewer can probe, reorder, or skip questions based on responses. Balances consistency with depth.
- Structured interview — fixed questions, fixed order, no deviation. Closest to a verbal questionnaire. Most consistent, least flexible.
